    - - constant wave action create pressure onto lines of weakness until rocks crack and shatter to form notches, over time waves continue to act on notch eroding it further deeper forming a cave, after some time, roof unable to support itself, collapsing, forming cliff with s wave cut platform(gentle slope )
    - - Erosion at the bases of headlands form caves and caves may develop at each side of the headland, further erosion joins the two caves. Further erosion prevents the roof of the arch from supporting itself, collapses and forms a stack separated from the headland
